Patented May 16, 1944 UNITED STATES PATENT OFFICE 'f l 2,349,195 v METAL DOOR CONSTRUCTION James. F. Peelle, Richmond, Ind. Application February `5, 1942, Serial No. 429,596 1 claim. (ci. 18e- 46) member enclosed therein.

A third object of the invention is the provision fofa metal door which is comprised of ya plurality of preformed members nested together and having an insulating member located therein, and With the assembled door being highly resistant to extremely high temperatures.

A further object of the invention is the provision of a fire-resisting door which Will meet the most exacting requirements of safety ordinances, which is economical to manufacture, which is simple of construction, and for which maintenance is substantially nil.

Other objects and advantages of the invention will suggest themselves in the course of the following description, and that which is new will be pointed out in the appended claim.

The most satisfactory means of carrying out the principles of the invention in a practical, economical, and eiicient manner is shown in the accompanying two sheets of drawings in which:

Figure 1 is an elevation of a door comprised of a plurality of preformed members in accordance with the principles of the invention.

Figure 2 is a detail section through the door, taken on line 2--2 of Figure 1.

Figure 3 is an enlarged detail section through one edge of the door, taken on line 3-3 of Figure 1.

Figure 4 is an enlarged detail section through the opposite edge of the door, taken on line 4-4 of Figure 1.

Figure 5 is an enlarged detail section taken on line 5 5 of Figure 1 showing the method of securing the preformed members of one face of the door to the nested-together portions of the preformed members forming the opposite face of the door.

Figure 6 is a detail vertical section, taken on line 6-6 of Figure 1, through the top edge of the door showing the method of providing lateral rigidity thereto.

Figure 7 is a detail section taken on line 'l-'I of Figure 1 showing the stiifening members provided in the lower edge of the door.

Figure 8 is a detail section through one of the preformed members.

Like characters Vdesignate like parts throughout the several views.

' In order that the construction and the vadvantages of the invention may be more fully understood and appreciated, I will now take up a detailed description thereof, in which I will set forth the same as fully and as comprehensively as I may.

Referring now to the drawings I designates preformed intermediate members, the major portions of which form the faces of the door.

Each of the members I has a portion 2 formed along one edge thereof and with a portion 3 being formed along the opposite-edge. It will be noted the portion 2 of one member I is adapted to nest with the portion 3 of the adjacent member I as shown in Figure 5.

One edge of the door is formed by the members 4 and 6 as shown in Figure 3. [Member 4 has a portion 2 formed along one edge which is adapted to nest into the portion 3 of the adjacent intermediate member, with the other edge 5 being formed at substantially right angles to the member 4 and forming one of the vertical edges of the door. Member 6 has a portion 2 formed along one edge thereof which is adapted to nest with the adjacent portionl 3 of an intermediate member I. The opposite edge I of the member 6 is formed at substantially right angles to the member and lies against the inner surface of the portion 5. A flange 8 is formed. on the edge portion 1, the purpose of which Will be hereinafter set forth.

The opposite edge of the door, as shown in Figure 4, is comprised of the members 9 and I0. Member 9 has the portion 3 formed along one edge with the portion 3 being adapted to lit around the edge 2 of the adjacent intermediate member I. The opposite edge II of the member 9 is formed at substantially right angles thereto and forms the edge of the door. Member I0 has the portion 3 formed along one of its edges and is adapted to t around and nest with the portion 2 of the adjacent intermediate member. A portion I2 is formed along the opposite edge of the member Ill with the portion I2 being adapted to lie against the inner surface of the edge II. The ange I3 is formed on the portion I2, the purpose of which will be hereinafter set forth.

It will be noted from the drawings that each side of the door is assembled independently of the other side. One side of the door is formed by laying the members together so their edges will nest together. A sheet of asbestos I 4 or other fire-resistant material is then laid in the assembled side of the door, after which the second side of the door is assembled by laying the members on the sheet I4 with their respective edges being nested together and with the portions 'I and I2 tting within their companion members 5 and I I respectively as shown in Figures 3 and 4. The flanges 8 and I3 lay against the edges of the sheet I4 and provide means of maintaining the edges of the sheet in their respective positions.

After thesides of the doors have been `laid tof gether with the 'sheet I4 being positioned therebetween, screws I6 and I'I are threaded into'the respective anges 8 and I3 with screws I6 secur. ing the members 4 and 6 together and clamping the edge I4' between the member 4 and the ange 8 and with screws I'I securing members 9 and Ill` together and clamping edge I4" between member 9 and flange I3, all as shown in-Figures 3 and 4. Screws I5 are extended through the side membersl I and through the sheet I4 and are threaded through the portions 2' and 3' of the members 2 and 3 respectively. After the members are assembled as above set forth the edges of members ,5 and II are welded to the respective companion members I and I2 at points designated by I8 and I9. p

The portions 2 and 3 are cut shorter at each end than the members I, 4, 6, 9, and I0 to permit the insertion of top stiiening channel members 20 and 2| and bottom stiffening channel members 22 j position as shown in Figure 6. Channel 2I is securely welded to channel 20 at the points designated by numerals 24. The bottom channels 22 and 23 are assembled into the door construction in a similar manner to that described above for channels 20 and 2l and are welded similarly at points designated by numerals 25 as shown in Figure 7. l

It will be noted that the vertically extending members 2, 3, 5, 1, II, and I2 provide rigidity longitudinally of the door with members 20, 2 I, 22, and 23 providing rigidity laterally of the door.

, The sheet I4, being of heat and fire-resisting l.each sidewbeing composed of preformed sections having inwardly-projecting nesting edges, a sheet of fire-resistant material positioned between the sides and secured in Xed position -between the .nesting members of one side and the inner face ofthe opposite side, and with screws extending through each side into the nesting members of the opposite siderand securing the sheet of firere sistant material therebetween.
